What Are the Easiest AP Tests To take and get 4-5s on??

Im a junior in high school. this year i only qualified for 1 AP class (US History). I want to study and take some other AP tests on my own since I have free time. What are some other AP tests that I can buy a textbook and study guide and get a 4-5 on it? plz be something related to math or science or something useful.

edit: I am willing to put in many hours of work, i just moved somewhere new and I have no friends atm

I recommend self-studying any of these:
AP micro/macro
human geography
environmental science (my friend took this and got a 4, self study. Works well alongside biology).
Psychology

Honestly, you could read the book 2 weeks before the test and score at least 3s on these.

Ok lol. AP Psych... is the ****ing easiest course I ever took in my entire school career (besides music appreciation lols). I literally did not study once for any tests, slept through the whole class almost every day, and got a 4 on the AP exam with no studying at all. AP Psych is by far the easiest AP ever. Totally agree with this list, except for micmac maybe (though I'd expect that self-studying for the APs is much easier than the classes themselves due to the nature of econ courses... big projects and sh*t like that.) Also AP human geography is like a joke. If you're really good at a language, you should probably take the AP for that too just to get credit (if u want, it's really up to you).
